The Astral Circlet increases the wearer's defense by 32 and maximum PP by 15. It can be bought for 4600 coins and sold for 3450 coins.

The Astral Circlet can be obtained shortly after beginning the Great Eastern Sea portion of the game. However, its usefulness is limited by the fact that Adepts who can equip it have naturally high PP levels. The Astral Circlet may or may not prove useful to an Adept not in his or her default class series. In the end, the Astral Circlet is best given to an Adept who uses Psynergy often. It will most likely be among the first pieces of equipment to be replaced, perhaps by the Crown of Glory, which restores PP during battle rather than simply increasing the amount of PP initially available.
